COMBINATION LAMP BURNER, CHIMNEY, AND CLAMPING DEVICE.

Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed July 12, 1916. Serial No. 108,896.

To all whom it may concern Be it known that I, ALVIN E. BROWN, a citizen of the United States, residing at Crayne, in the county of Crittenden and State of Kentucky, have invented certain new and useful Improvements in Combination Lamp Burners, Chimneys, and Clamp ing Devices, of which the following is a specification.

This invention relates to improvements in illuminating devices, and pertains especially to novel improvements in lamp burners, chimneys, and means for attaching or connecting the same.

The object of the invention is to provide a lamp burner and chimney having certain construction and shape relative to each other and relative to a particular device for connecting the chimney with the burner, and to furnish a novel and peculiar clamping device specially constructed for the burner and for the particular chimney hereinafter described and shown in the drawings.

The ordinary type of chimney and burner require loss of time and labor, and much experimenting in assembling so that one will fit the other with any degree of security, and require repeated adjustment from time to time to prevent loose fitting or liability of displacement. It is well known that the ordinary burner fingers for a chimney are of disadvantage, especially in that the fingers are subjected to the heat from the burner and consequently are impaired and often rendered useless for securely and properly holding a chimney in position. It is also well known that the fingers obstruct the light, that the fingers have to be adjusted for holding a chimney to a burner, and that the usual chimney-clamping devices have to be'operated in placing and removing a chimney.

My invention is intended to remedy, overcome and avoid all of said objections, disadvantages and inconveniences, and to furnish a combination burner, chimney, and device for clamping the chimney and burner together, which shall be permanent, reliable and of such individual character as to be expeditiously used in connection with ordi proved results will be found in the practical application of the invention now to be described in detail.

In the accompanying drawings forming part of this application :Figure 1 is an elevation of a clamping blank as struck out of one piece of metal preparatory to shaping and finishing for application. Fig. 2 is a perspective view of the clamp as applied to a burner. Fig. 3 'is a sectional elevation showing the application of the clamp to a burner and a chimney. Fig. 4 is a detail elevation of the chimney base. Fig. 5 is a detail perspective view of the spring-catch. Fig. 6 is a top view of a modified burner flange.

The same reference characters denote the same parts. throughout the several views of the drawings.

In order that the chimney, the burner and the clamp may not be used independently,

and that the same may only be used in conjunction, I have devised'certain relative con struction in the several partsfor the successful cooperation thereof. v

The body of. the chimney 1, may beof any desired shape, but the base of the chimney has an annular swell or off-set 2, at a distance from the bottom edge or periphery of the chimney equal to the height of the clamping device hereinafter described. Above the off-set and between the latter and the body of the chimney there is a narrow neck 3, the purpose of which will hereinafter appear.

- The base 4 of the burner has a screw portion 5, the burner is without the usual prongs or chimney-holding fingers, and the burner cap 6 is attached in the usual manner. The base 4 has an annular flange 7 upon which theclamping device rests, and the chimney is seated on this flange of the burner, and

over a shoulder 9 adjacent to the said flange.

The flange 7 has a special peripheral edge 10, of such size and shape as to have certain members of'the clamping device engage over and under said edge, without engaging the chimney.

The clamping device is die-stampedout of one piece of sheet steel adapted to be bent and tempered in circular spring form. The longitudinal cut outs 11 are separated by a central vertical bar 11 and by vertical bars 12 connecting the top 13 with the bottom 1 1, and these top and bottom members const1- tute resilient connected rings, adapted to be.

opened, closed and locked on the burner as will be hereinafter explained. The bar 11 and the bars 12 are bowed'or curved so asto.

extend over the swell or off-set 2 of the chimney without engaging the latter or the off-set.

ings and centrally between this end. of the members or rings 13 and 14. Abail or. lever 23 is pivoted, in. the bearings 21, andthe lat ter with the tongue and the lever. is passed through the slot 17, so that the tonguehas over-lapping engagementv with one. of the bars of the pair of. bars 16, and the. inner edge of the other or outer of said bars engages under the bearings. I The bearings are flattened or otherwise made so as to produce an eccentric or cam movement of the lever, or the pintlesof the lever 23 may be cam shaped, .for holding the lever in locked position over the said outer bar. A catch 24 is pivoted in theears 19. opposite the bar 11,

and has a lip 25, of the same. shape as the lips 15, and like the latter, projects over and under the flange edge 10 of the burner. The catch is controlled by a spring 26, and is operated for placing and removing the clamping device without unlocking said.de-. vice.

Referring to the modification shown. in Fig. 6 of the drawings, the burner flange 28 has a plurality of slots 29 thereiinthrough which the lips. of the clamping device, hereinbefore described, extend, for connecting the clamping device with. the burner; Other forms of burners may have. either of the flanges for applying the clamp.v

While I prefer to usea bottom ringmember wider than the top ring member, said members may be of the'same width. The top member makingthe only engagement of the clamp with the chimney.

I do not wish. to be understood as confining my invention to any particular. size or material, to the width of the rings, to the number and location of the lips, or to the number andlocation of the ring bars, nor do I wish to be limited in the application of the invention to any particular lamp or lamps, but reserve to'myself. the right to make such changes and: variations in the practical manufacture and application of Projecting from the bottom edge of the bottom ring or member 14, are hookedthe several parts, as may come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1.. The combination with a fingerless lamp burner embodying an annular flange forming a chimney base seat, a chimney having anannular off-set and a neck above the ofl-set, of a clamping device comprising'top and bottom resilient rings, vertical bars connecting and spacing the rings with respect to the said off-set, lips projecting from the bottom. ring for locking engagement with the said flange,,a spring operated lip on the bottom ring, and means for locking the members in-closedposition so. as to. engage a the top ring with the. chimney neck above the offset 2.. The combination. with a fingerless burner embodying an annular flange having a lip-engaging. periphery and a chimney for loosely fitting the flangeand having anannular ofi -set. and a neck above the offset, of a clamping. device comprising a pair of vertically connected rings, one of the rings adapted to extend over the off-set for. making the only engagement of. the clamp. with the chimney, a plurality of hooked lips pro.- jecting. fromthe bottom edge of the other ring. and fitting; said flange periphery, a spring-operated catch-lip mounted on this ring, and means for locking the. rings in closed position.

3. A clamping. device for lamp chimneys and-lamp. burners, comprising a pair ofzresilient members spaced apart, a pluralityof vertical bars connecting the members, apln. ralityv of burner-engaging lips projecting from. one of the members, a pair of vertical bars having a slot therebetween and connecting one end of said members, a plate connecting the other end of said members,a pair of bail bearings formed on the plate for engaging one of the end bars, a tongue projecting from the plate centrally between the bearings. for engaging. the slot, and a locking. bail pivoted in said bearings and adapted-to extend through said slot for looking. engagement with the said end bar. 7

4. A clamping device for lampchimneys and lamp burners, comprising a pair of resilient members spaced apart and connected vertically, a plurality of burner-engaging lips-projecting from oneof the members, a pair of ears struck out of this member, a
